Khuk Khi Kai (Thai: คุกขี้ไก่, pronounced [kʰúk kʰîː kàj]), also called the Chicken Dung Cell or Chicken Poop Prison, is a former prison in Laem Sing, Chanthaburi, Thailand. It was built by the French in 1893, when the French occupied the area as part of the Franco-Siamese conflict, to imprison Thai resistance fighters.[1] The square-shaped tower is made from red bricks and is 4.4 metres wide and 7 metres tall, with two rows of slits along the sides.[2] The tower was abandoned after the French withdrew in 1904.[3][4]
The resistance prisoners were kept on the ground floor of the tower. Above them was a chicken coop. The floor between them was perforated meaning chicken faeces were able to fall down on the prisoners below, as a form of torture.[5][6]
